Scanner Changes Colours only when scanning to PDF

[headstrong4]

I have the exact same problem reported in this thread. https://h30434.www3.hp.com/t5/Scanning-Faxing-Copying/Scanner-Changes-Colours/m-p/6726796#M192577. The scanner changes colours when scanning to PDF only. Black and white images change to green. Similarly Red changes to green and blue changes to Red. Overview scan is fine and JPEG scan is also fine. 

It looks like this problem never got a solution. I am not sure what the support specialist is asking to try in the last comment. I need to scan important documents for my work and it looks completely unprofessional with the colour change. Please help to provide a solution.

@headstrong4, Welcome to HP Support Community!

Have you tried using the Apple Image Capture App? If no, follow the steps below-

Apple Image Capture comes with macOS and OS X and provides a quick and simple way to scan.

1. Place the document or photo print side down on the scanner glass, and then close the scanner lid.

   If your printer has an automatic document feeder (ADF), use it to scan multiple page documents at one time.

      CAUTION: 

   Do not load photos in the ADF.

2. Open Finder , and then click Go in the top menu bar.

3. Click Applications, and then double-click Image Capture.

4. Click your printer name in the Devices or Shared list.

   NOTE: 

   If a Software for this device is not installed message displays after you select your printer, click Install, and then follow the instructions to complete the installation.

5. Click Show Details at the bottom of the screen.

   A preview of the scan displays, and then change any of the following settings:

   • Scan Mode: Select the scanning bed or automatic document feeder.

   • Kind: Set scan as color, black and white, or optimized for text only documents.

   • Resolution: Higher resolution produces better quality images by using more dots (pixels) per inch. Higher resolution increases the file size of the scan. Use a higher resolution for scans with graphics or items that require the best detail. If you are scanning black and white text, higher resolution is not necessary.

   • Size: Use a standard paper size or select the Use Custom Size option.

   • Scan to: Select the folder you want scans to save to or use the Mail option to attach the scan to an Apple Mail email message.

   • Name: Type a name for the saved scan file.

   • Format: Select the file type for the scan.

     NOTE: 

     To save multiple page documents or multiple images into a single file, select the PDF or TIFF format, and then select the box next to Combine into single document. This feature is only available with these formats.

   • Image Correction: Click the pop-up menu, and then select Manual to display color change options such as brightness and saturation.

6. Click Scan.

See if that makes a difference.
